The Hobbit and DefenceForce are now compatible:

The Demo program is a special multipart file, then it is not compatible.

I If the sound files are recorded with this tape recorder, to reread them it is not necessary to adjust the head azimut, there is a problem of fouling the reading head, various speed, or a bad setting of the equalizer (bass or tweeter). For a best control, just save a HIRES screen with a lot of deta...

The Oric computer doesn't need its Rom chip. But Erebus needs two banks of 16k memory each.

In this case A14 replaces A15 on pin1, this is not a problem for the selection of bank0 and bank3, but the pine27 is problematic with the process, this pin must be disconnected. For the program, Bank0 is the same but Bank3 become the bank1. The content $C000 to $FFFF in the 27c512 chip is placed at ...

After all these years of hard work by Jede we will have a concentrate of all the real Oric peripherals in one device.
Long live the TwilighteCard !

The value of the resistor is 220 ohms. The Sd module is the same for the 3D-printed case. I suppose that Mustangus soldered the 6pin connector on the opposite side of the pcb and the bent model was chosen. We can solder directly the sd "Catalex" module on the main board but there is the risk of elec...

On these components it's very poorly printed ... Good news!

Kenneth, can you provide location in ROM to fix it?

In the Erebus file the Oric Rom code begins at the same place as the Basic11b Rom file, then you must replace these bytes:
Adr $3934:
#1E before, #1C after.

Adr $39CA:
#1A before, #18 after.

can you send the pictures of the ribbon and of the interface with the both sides?

Magnifique !

Normally the chips have supports, I designed the pcb to install a ZIF support for those who want to program the Uvprom.

About the Erebus device, the Atmos Rom which is in the chip 27c512 is the same, only the Cload routine is modified.

Are there the 4 bridges on the top of the pcb?
Maybe a chip or the diode mounted upside down?

The computer uses the 50Hz frequency for the screen, the POKE will set the ULA ship in the 60Hz mode video for US country, in the HIRES mode,I suppose that the routine will switch the ULA in the 50Hz mode because of random poxels. You must burn an Uvprom with a little code to switch the both resolut...

Very interesting, for me it was midday, I had to slip away during the demo of JeDe (I apologize to him, the meetingmaster and the other guests) the hp and the microphone were deactivated and reactivated just in time . I can't wait to see the entire YouTube version..
